Even though they recently managed to hit the 754 whp mark with a Torch Red Stingray and believe it already to be one of the most powerful C8s in existence so far, FuelTech says they’re far from satisfied and hope to pass 1,000 horses before it’s said and done.
Since Tadge Juechter and his team at Chevrolet have made the factory ECU nearly impossible to crack so far, FuelTech USA decided to integrate an FT600 ECU to control a supplemental fuel supply and other engine functions and manipulate the stock ECU readings.
That means it’s possible to add turbochargers and superchargers and finely tune the engine for maximum performance. The FT600 also provides “an incredible amount” of data thanks to a full suite of FuelTPech and OEM sensors.
Besides the FT600, the company basically used everything but the kitchen sink on this car, including two WB-02 Nano sensors in the exhaust to monitor air/fuel through a Bosch LSU 4.2 sensor hooked to the FT600 through a CAN bus connection.
Also wired into the FT600 are a backpressure canister, 150-psi pressure sensor to monitor the port fuel injection, two backpressure sensors for each turbocharger, turbocharger speed sensors, and a FuelTech EGT-4 with individual cylinder EGT monitoring to help with complete data collection and engine safety.
The FT600 controls an auxiliary set of 1050cc/min fuel injectors (one in each port) and an independent Aeromotive fuel system—complete with its own fuel cell, fuel lines, and brushless 5 GPM spur gear electric fuel pump. The Aeromotive pump has a low-speed mode for normal driving conditions, and the fuel pump speed is increased when under a load. The FT600 handles all of the fuel pump control.
FuelTech decided not to add an intercooler, opting instead for a VP Racing Fuels M1 that acts as alcohol injection to keep the inlet air temperatures cool enough.
The engine is said to remain safe in normal and spirited driving conditions thanks to the FuelTech 02 correction that works along with the factory ECU to create the perfect air/fuel ratio at all times. The factory OEM computer still controls the direct injection of VP Racing Fuels MS100 unleaded gasoline from the factory tank, with the FT600 manipulating certain sensors.
FuelTech installed a couple of Garrett G35-900 mirror image turbochargers as part of a custom-built kit, with assistance and consulting from the LMR top-mount turbo C8 Corvette.
By the way, since FuelTech hopes to surpass 1,000 horsepower before they’re through, they also fortified the LT2 V8 engine with GPI drop-in forged Diamond pistons and connecting rods and also upgraded the rear axles to a pair of GForce Performance Engineering axles.
FuelTech believes the stock clutch is capable of handling up to 750 whp but plan to replace it with a more durable clutch under development by Dodson Motorsports on their way to more than 1,000 whp.
Also under development is a C8 Corvette jumper harness to allow easy installation of any PowerFT engine management system while retaining factory electronics.
